I was using plastic pipe in the past (filled with concrete and couple of steel rods with threads at the top, to fit the mount) and I was very happy with the setup.
I am planning something like that for my yard in the near future.....

Whooops – thanks for that!
I should really have written that I made a transportable pier, with 3 bolt on legs, although I have since considered a permanent pier in the back garden. Glad I didn’t now.
Just out of curiosity, over what time period would a catastrophic failure be expected to occur? Say 12 months, 3 years, 5 years or greater?
Thanks!
